Offshore Wind Energy for Humboldt County
Humboldt County’s expansive coastline is home to one of the greatest offshore wind resources in the nation. Humboldt County has been featured in local, national, and international news since 2018 as a potentially ideal location for offshore wind energy generation. RCEA, tasked with developing local renewable resources and energy-related economic advancement, has been leading an extensive planning and research process for what could be California’s first floating offshore wind project.
In May 2021, the Biden-Harris Administration announced an agreement to advance areas for offshore wind off the northern (Humboldt County) and central coasts of California. This significant milestone is part of the Biden-Harris administration’s goal to create thousands of jobs through the deployment of 30 gigawatts (GW) of offshore wind nationally by 2030. The environmental assessment and lease auction process is being managed by the Bureau of Ocean Energy Management (BOEM).
Redwood Coast Offshore Wind Project
The Redwood Coast Offshore Wind Project is an initial commercial-scale project proposed by RCEA and a consortium of developers.
In 2018 RCEA issued a Request for Qualifications for development partners, through which RCEA’s Board of Directors selected a consortium of companies to work with to pursue local offshore wind energy development.
RCEA and the consortium submitted an unsolicited lease application to the Bureau of Ocean Energy Management (BOEM), which is responsible for offshore wind energy leases in Federal waters. Although the lease application was not accepted, the lease area proposed by RCEA was subsequently absorbed into the Humboldt Wind Energy Area which will be leased through an auction in late 2022. The consortium later formed a project company, Redwood Coast Offshore Wind LLC, in which RCEA remains a partner.
The project company is working closely with local stakeholders to design a project that minimizes impacts and maximizes local community benefits, should it be awarded a lease. After that, the work of designing and developing a project will take years to complete and will be the product of extensive community collaboration. While conversations with local fishermen, Tribes, environmentalists, labor unions, and government partners are ongoing, our community’s overall response to this prospective project has been supportive. RCEA is committed to advancing the development of our offshore wind resource in a responsible manner that addresses the concerns of the local community and impacts on the environment.
Why Offshore Wind?
- The North Coast has a world-class offshore wind resource
- Floating turbine technology is now available to unlock its potential on the Pacific Coast
- Offshore wind diversifies the renewable energy portfolio needed to cut California’s greenhouse gas emissions
- Humboldt Bay is well suited to serve as a hub for a broader west-coast offshore wind industry
Redwood Coast Offshore Wind Project
- 100-150 MW
- about 25 miles west of Eureka
- 2,000 to 3,600 feet seafloor depth
- Provide competitively priced renewable energy to electric ratepayers
- Prioritize stakeholder engagement and acceptance; identify and address issues of local concern
- Develop responsibly and minimize environmental impacts
- Maximize investment in local infrastructure to develop Humboldt Bay into an industry hub.
Humboldt Wind Energy Area
Selected based on the following factors:
- Approximately 205 square miles to accommodate project size (The ultimate lease blocks will be determined by the Bureau of Ocean Energy Management during the 2022 lease auction process)
- Existing commercial fishing and shipping uses
- Wind resource maps
- Wildlife and habitats
- Technical constraints, such as minimizing grid interconnection distance
- 5 to 15 turbines – (TBD based on final project and turbine sizing)
- Anchored to the seabed using synthetic mooring lines
- Inter-array cables connecting turbines to each other
- Export to shore via subsea transmission cable (exact landfall location TBD)
- Interconnection at Humboldt 115kV substation
- The best port site to support the project would be the Redwood Marine Terminal 1 (RMT1). Upgrades would be required; the Humboldt Bay Harbor District is developing a conceptual plan.

The Project Partners
Aker Offshore Wind is a leader in the development of deepwater offshore wind power production. They are a Norwegian offshore wind developer striving to create a sustainable future – one driven by clean, green energy. Check out Aker’s new video, they’ll take it from here.
RCEA works to develop and implement sustainable energy initiatives that reduce energy demand, increase energy efficiency, and advance the use of clean, efficient and renewable resources available in the region for the benefit of the Member agencies and their constituents.

What About the Fishing Industry?
The North Coast region is home to a commercial fishing industry that provides sustainably-caught seafood to our community and many others. For many generations these commercial fisheries have provided a livelihood for local fishermen and their families, and it continues to be a key element of our region’s economy and local culture.
The Redwood Offshore Wind consortium recognizes that a viable commercial fishing industry is integral to the economy and culture of the North Coast and that the development of offshore wind energy will permanently impact the commercial fishing industry economically and culturally. We recognize that such development should be pursued in a manner that minimizes and mitigates impacts to fishing so that both endeavors can sustainably coexist for the benefit of our community. Both the consortium and the Humboldt Fishermen’s Marketing Association agree to cooperate and work together in good faith for the purpose of ensuring that the efforts of RCEA and its project partners to develop a floating offshore wind energy project off the coast of Humboldt County proceed in a way that effectively identifies, avoids, minimizes, and mitigates impacts to the commercial fishing industry to the greatest extent possible.

Fishing Community Sustainability Plans – Fishing community sustainability planning for Eureka and Shelter Cove
Fishing Industry Facts:
- Although the number of registered commercial fishing boats in the Humboldt Bay area has declined from approximately 500 in the 1950s to approximately 220 in 2004, the bay is still an important port for commercial fishing.
- More than 500 vessels from other West Coast ports use the bay’s facilities annually. The commercial fishing fleet is based at Woodley Island Marina, the City of Eureka Marina, and to a lesser extent, the private King Salmon Marina (HBHRCD 2007)
- Commercial crab fishing is highly active in nearshore waters off Eureka and makes up the overwhelming majority of Eureka commercial landings and ex-vessel revenue between 1992 and 2014 (Hackett et al. 2017).
- Groundfish trawl fisheries occur at greater depths, generally in water depths less than 600 fathoms (1100 meters), with an average depth of <300 fathoms (550 meters) (Sommers et al. 2016).
- Since 1981, total pounds of all fish landed in Eureka has dropped from a high in 1981 of 36.9 million pounds to on average 1.9 million pounds between 2001 and 2007; most of the decline was due to a decrease in groundfish landings (Pomeroy et al. 2010).

Additional Information and Resources
Does RCEA’s long-term contract for 100 MW of solar energy from the Sandrini Sol 1 project preclude RCEA contracting for offshore wind when that becomes available?
RCEA’s goal is to have a diversified power mix, and this long-term solar power purchase agreement is an ideal complement to offshore wind in a number of ways. The solar contract’s price per unit of energy is lower than we expect offshore wind to cost, but offshore wind’s time-of-day production better matches our customer energy demand throughout the day. In addition, the location of the solar project allows it to avoid the transmission access challenge that large-scale renewable energy generation sited in Humboldt County faces, due to our remoteness from the state’s main transmission corridors.
The Sandrini contract helps us meet our near-term SB350 compliance targets, which requires us to secure long-term renewable portfolio standard contracts, and it does so in a very cost-effective way. We could not have waited for offshore wind for this purpose, given the long development timeline. About half of RCEA’s portfolio remains open for long-term contracts.
